SAWMILL-REFUSE BURNER.

Specification of Letters IatentQ Patented Sept. 6, 1910.

Application filed May 7, 1910. Serial No. 559,892.

To allwhom it may concern: I

Be it known that I, ARTHUR B. DrPLooK, a citizen of the Dominion of Canada, residing at North Vancouver, in the Province of ,British Columbia, Canada, have invented a new and useful Sawmill-Refuse Burner, of which the following is a specification.

This invention relates to a burner for the destruction of the wood refuse of a saw mill and is designed to provide a simple, effective and inexpensive means to effect this object. These burners are usually built of brickwork bandcd or sheathed with iron to hold the brickworktogether under the expansion and contracti'en due to the heat of the furnace. This construction in a large sized burner is quite an expensive one and necessitates a substantial foundation. It is to supply a burner at a comparatively small cost that the construction and novelapplt cation which are the subject of this application have been designed.

The invention is particularly described in the following specification, reference being made to the drawings by which it is accompanied, in which:

Figure 1 is a vertical cross section on the line A A in Fig. 2, F ig..2,is a plan view of the burner, partsbeing broken away. Fig. 3, an enlarged detail of one of the air trenches with its grate bar, and Fig. 4

is an enlarged detail showing a means whereby the corrugated sheet metal may be connected to their strengthening bars.

The walls 2 of the burner are formed of corrugated sheet iron the corrugations of if found necessary by wing screens extended,

toward the prevailing winds.

Between the inclosing walls 2 of the burner, the trenches 3 are provided with gratings 5, that will give the air access to the fire and that will prevent the mill refuse, which is delivered into the burner by a conveyer in the usual way, from filling the trenches. Y The bottoms of these trenches are lined as at 4, see Fig. 3, with sheet metal so that the water may be flushed through them from-one'side to the other to clear away the "ash falling through without. scouring the mortar from the brickwork.

. Around the upper edges of the corrugated walls 2 is carried a water pipe 6 provided -with perforations directed downward and outward upon the inner sides of the walls. This pipe 6 is connected to a water service 8 by a pipe 7 at each corner so that while the burner is in use the walls are kept cool by a spray of water 10 directed on them.

The gist of the invention resides chiefly in the walls of vertically corrugated iron with the water spray by the use of'which this construction is rendered available and the narrow grating covered air supply trenches which are made so that the expense of thegrating may be kept low.

Corrugated metal is selected to form the .walls as it is largely self-supporting andas it enables the water trickling down the inside to pass any slabs of wood which might be lying against the inside, and which with necessary with irons 11, are practically selfa flat surface would divert the water from supporting and will expand readily with the heat without excessive buckling and are prevented from being overheated by the water' spray against them. The vertical corrugations will also prevent slab wood 01' the like which may be lying against the sides from preventing the cooling water from passing down. The walls, askept cool in this manner, will lastalong time and the trenches may be readily flushed by means of a hose to remove accumulated ash from them.

Having now particularly described my invention and the manner of its use, I hereby declare that what I claim as new and desire to be protected in by Letters Patent 1s:

1. As a burner or destructor for saw mill refuse, an inclosure walled with corrugated sheet metal, means for delivering water on walled inclosure of .the walls, an

ground surface which is inclosed by the wall, said trenches being extended laterally beyond the walls.

2. As a means for the'purpose specified, a wall inclosure of corrugated sheet metal the corrugations of which are vertically arranged a water pipe located at the top of the wa s said pipe being perforated to deliver a spray against them, trenches formed of brick extending across the surface of the ground which is inclosed by the'walls said trenches bein d gratings .over the within the inclosure. 3. As a means for trenches the purpose specified, a corrugated sheet metal, means for spraying water against the inner surface of the walls, relatively narrow trenches formed of brick across the bottom extended laterally beyondof the inclosureand extending laterally beyond its walls the lower part of said trenches being lined with sheet metal.

4. As a means for the purpose specified, a walled inclosure of corrugated sheet metal forming a combustion chamber, metal bars extending across the corrugations on the out-- side which bars are secured at intervals to the corrugated sheet metal, means for spraying water against the inner surface of the walls and means for delivering air to the ground area within the inclosure.

In testimony whereof I havesigned my name to this specification in the presence of two subscribing witnesses.
